Method and apparatus for controlling fluid flow in conduits

摘要: A completion string for use in a wellbore includes main conduit, such as production tubing, and one or more alternate path conduits, shunt tubes, that extend generally parallel with the conduit. flow control device is positioned each conduit to through The conduits may be adapted carry gravel slurry perform packing operations. devices actuated open position allow communication of multiple zones wellbore. Once operation completed, closed block fluid between during well. Other types fluids communicated fracturing fluids.
